What is the role of experiences during critical periods in temperament?

• A. Critical periods have no effect on temperament
• B. Experiences during critical periods influence temperament
• C. Critical periods only affect physical traits
• D. Critical periods are the same for every dog

Answer: (B)

Experiences during early development create lasting patterns in temperament because there are windows of heightened neuroplasticity known as critical periods. In these times, a puppy’s brain is especially receptive to environmental input, and the quality of handling, socialization, and exposure to people, dogs, new environments, sounds, and objects can shape how they respond to the world later on. Positive, varied experiences during this window tend to foster confidence and sociability, while limited or negative experiences can lead to greater fear or reactivity that can persist. Genetics set a baseline, but what the puppy experiences during these critical periods can significantly influence the eventual temperament.
